vercel: Python error when deploying

When i was deploying django app on vercel i got this error

Error! Unable to find binary python3.8 for runtime python3.8 Error! Check your logs at https://komputama-qj1unu7v1-ngapa.vercel.app/_logs or run vercel logs komputama-qj1unu7v1-ngapa.vercel.app

And the log in the deployment status is

This is my ‘vercel.json’

{ “build”: { “env”: {

    }
},
"builds": [{
    "src": "cores/wsgi.py",
    "use": "@ardnt/vercel-python-wsgi",
    "config": { "maxLambdaSize": "15mb", "runtime": "python3.8" }
}],
"routes": [
    {
        "src": "/(.*)",
        "dest": "cores/wsgi.py"
    }
]

}

I got stuck with this, so anyone help me?

Hey @Ngapa use the official python runtime i.e.@vercel/python. add app = application end of cores/wsgi.py because the official python wants to expose the your wsgi/asgi application via app’ more details on python runtime

@MayankSuthar1 go to vercel.com, pick a project and then go to Settings > General -> Node.js Version. Pick 18.x

Change node.js version to 18.x in project settings works for me.

I also faced this same error and also i followed step provided by @prabincankod of adding app = application and setting python version to 3.9 , but still getting this issue. Also i am using the official @vercel/python Edit 1: This is the error WARN!

Change node.js version to 18.x in project settings works for me.
